AD8341RF/IF射頻/中頻RFID的RF調(diào)制器規(guī)格書(shū)PDF中文資料

AD8341屬于RF/IF射頻/中頻RFID的RF調(diào)制器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8341RF 調(diào)制器射頻 (RF) 調(diào)制器產(chǎn)品用于通過(guò)更改載波的幅度、相位和/或頻率，將信息編碼到正弦載波信號(hào)上。執(zhí)行反向解調(diào)操作的接收設(shè)備會(huì)選擇性地以所需載波頻率接收傳入信號(hào)，從而將載波屬性的變化轉(zhuǎn)換回原始形式。這樣的配置允許使用通信通道來(lái)同時(shí)傳輸多條消息，而彼此之間沒(méi)有干擾。

GENERAL DESCRIPTION

The AD8341 vector modulator performs arbitrary amplitude and phase modulation of an RF signal.

Since the RF signal path is linear, the original modulation is preserved. This part can be used as a general-purpose RF modulator, a variable attenua tor/phase shifter, or a remodulator.

The amplitude can be controlled from a maximum of ?4.5 dB to less than ?34.5 dB, and the phase can be shifted continuously over the entire 360° range.

For maximum gain, the AD8341 delivers an OP1dB of 8.5 dBm, an OIP3 of 17.5 dBm, and an output noise floor of ?150.5 dBm/Hz, independent of phase. It operates over a frequency range of 1.5 GHz to 2.4 GHz.
